Is it possible to add a standard-looking badge to a standard UIButton
?
If it's not supported semi-natively, what would be the simplest way to achieve this?

Here's a VERY NICE class by Sascha Paulus called CustomBadge, that builds and renders custom badges using Core Graphics. They're just UIView subclasses, so you lay them out using their frame just like any other UIView subclass.
I've used this library many times and always been pleased with the results. Flexible, easy to use. Totally recommend it.
